Chapter 5. Digital Signaling Principles

Introduction

In Chapters 2 and 3 we learned that the first step in designing a communication system is to ensure adequate power transmission between locations. From engineering practice we developed some insight into how to optimize power transfer to obtain efficient communication links that can operate in the presence of noise and transmission impairments such as shadowing and multipath reception. In Chapter 4 we learned how frequency reuse enables the design of communication systems that serve multiple users over a growing geographical area. We are now ready to consider how information can be transferred across the links in such a communication system. We postpone consideration of what the information might ...
